The tension that the Park meter gave you seems alright Andy. Usually the max number you don't want to go over for your wheels is 25, with that tensionmeter. And I agree that the eyelets having little cracks isn't something to be concerned about immediately, as in soon-to-be death, but the cracking of the actual rim is pretty nasty. I would def. look into getting a new wheel or wheelset, like you said you were.

Curious though... did you stress relive and check if you need re-tensioning before riding them?

Take care dude.
